Strange, only 8 days ago I was told this on HN “Most emissions from modern vehicles these days comes from things like tire dust rather than tailpipe. What would be best for local street level pollution would probably be something like a lightweight rickshaw over a multiton EV.” https://news.ycombinator.com/item?id=34540177 https://news.ycombinator.com/item?id=34540177

There’s nothing strange about it. EVs are better than IC cars but still not good on all metrics.

That is not a discordant take. Pedestrians and cyclists are obviously the most pleasant transportation option to be around in an urban space acoustics/particulates emissions wise. Unfortunately, some places have gone all-in on cars and it is literally impossible to live a full life without using one. This is where EVs slot in nicely. Further, EVs that fit into the micromobility space are an excellent option for many places-- e-bikes, scooters, Renault Twizy, etc. (Which aligns with what you were told above)

That’s only true for particulate emissions. ICE cars produce much nastier stuff than particulates, and EVs eliminate those classes of pollutants. On the particulate front: EV’s greatly reduce brake dust, but increase tire wear. The market will partially address the latter. Tire wear on my EV costs $0.15 per mile, and I’ll certainly be taking that into account when I buy my next car!

  That can’t possibly be true. A new set of all season tires is like $2000. You are going through a set of 4 tires every 13k miles?

    $2000 for a set of all seasons? I thought I was spending a lot of money when I dropped $1100 on a new set for my Model X. That works out to about $0.024 per mile for me if they last as long as the last set of the same make and model. (About 48k) So, maybe that poster meant $0.015 per mile, not $0.15?

      CrossClimate2s or don’t even bother. ;) https://youtu.be/PT2odY3C6Og https://youtu.be/PT2odY3C6Og

        What tire sizes are you buying? My CrossClimate2s were less than $1k for a set of 4

    Depends on size. R14 garbage is still under $75/tire. Some fat R19s for your 'vette, yeah those will cost you.

  The tires on my last EV needed replacing at about 25K miles, and those were the OEM tires which tend to wear out quicker than retail tires. I think I spent about $700 replacing all four. That's about 3 cents per mile. If the replacements lasted their 70K mile warranty, that'd be only a penny per mile.
